Hello all, I have in a job lot a HP ProBook 640 G8, one of the bios chips is missing and I am not
sure the chip that's fitted is even the original chip looks like its been replaced.

SN, 5CD1360KBZ
MB, DAOX8QMB8E0 REV E

Is there any hope for this laptop? I have tried every set of chips I can find with no luck.
Anyone have a good working set they could share please.

Thanks.

What are the silkscreen markings for both, are there numbers like U365 or writing such as Bios1 EC_Bios .Backup the chip thats there and open it with HxD, download the bios from post 1 and open that as well, scroll through each one, if yours is a close match then it`s the main bios, but not necessarily the right one. Search for the serial number in the bios with HxD, a text search,and for the Text encoding option select Unicode ,if the serial number is found thats good. The main bios at post 1 has 3 chips in the VSCC table, see the picture below

Thank SMDFlea for trying to help on this one, It turns out the bios chip I have is the original.
I have got this info from the bin file, the mac looks a little odd to me.

Product Name : HP ProBook 640 G8 Notebook PC
Serial Number : 5CD1360K8Z
Product Configuration ID : 2Q013AV
BuildID : 20WWISDT601#SAK8#DAK8
FeatureByte : 3X476J6S6b7B7H7M7Q7W7m7saBaEapaqauawbUbhcAdUdpdqfAfPguhKhkjhk8mEn7nVpD.r7
System Board CT Number : PKXXL058JFM0RN
MAC Address : 88-88-88-88-87-88

I think the bios file at post 1 is a EC bios file and the one I have from the laptop is the Main bios.

Any more help would be really good as not sure what now, do I try both files together in the laptop see if it displays anything?

Thanks so much mate. I added my main bios may help.

Try these, flash both.

[Dan20701]

Hello SMDFlea thank you so much for your help, sorry I have been away for a few days, tested these files
all I get is an orange flashing led near the power supply, no post if anyone has any ideas that would be great thanks.

thanks again mate .

[dandymon]

I'm in this exact pickle too, did you get anywhere?

[Dan20701]

No mate, it's still sitting here in bits may need another board or sell it for scraps.
There are not many sets of bios files online for this model, DAOX8QMB8E0 REV E
and I tested all I could find. didn't think to try a set for a another board model maybe I give this a go.
if you should fix please share.
